Thank you guys from OP. While watching a YT video "Do's & Don'ts on Turbo" I read a comment from one who watched the video to floor the gas pedal from time to time in order to lube the Turbo. Is this true? It sounds a little crazy.
Yep, that’s crazy. Oil pressure is oil pressure, oil pump output is what it is, so the turbo is getting lubed the same at the same engine RPM regardless of turbo RPM.
Another example of YouTube morons masquerading as experts.
The best thing you can do for turbo durability, is to allow the engine to idle for a solid 15-20 seconds before putting the car in gear, and drive it gently until the oil temperature has stabilized, around 15 minutes into your drive.
This ensures that the turbo charger has a good oil supply before it’s asked to spool up and provide power, and you keep it from going to max rpm until the oil temperature is stable.
Additionally, when you go to shut down the engine, especially if the car has been driven at high speed, or full throttle, is to allow the engine to idle for another 30 seconds or so, before shutting it off. This ensures, that the turbo RPM has a chance spool down, and you keep oil flow to the turbo, while it spins down.
Even better, is to drive it gently for the last five minutes of your drive, then let it idle for a few seconds, then shut it off, that way the turbo will be completely cool and spooled down, when the oil supply is shut off.
My wife is not a car person. But her Volvo XC is a turbo charged car approaching 300,000 miles on the original turbo charger. It sees a lot of short trips, and around town driving.
Her drive is perfect, we have a very slow speed street for about half a mile, before she pulls out on a medium speed road. The car is driven as I described above, because of the nature of her commute. So, the turbo charger isn’t stressed until the engine is warmed up and she gets on the freeway 10 minutes later, and when she comes home, the car is driven very gently for the last five minutes before idling in the driveway for a few seconds and shut off.
A little bit of care and consideration for the turbo charger has resulted in a very long life.
